I think this game might have my favorite use of the theme so far. As others have said, the malfunctioning does not really feel like a significant part of the puzzles, or anything like that -- but that's what makes it so good, in my opinion. This game really does feel like playing as a malfunctioning robot. The malfunctions are not significant in some special, predestined way... they just are a fact of life for this robot, and we get to experience that by playing this game. I think that's really cool, and I really enjoyed that aspect of the game. I mean: seriously! I felt like I was a malfunctioning robot for real! It's a great encapsulation of that experience.

The raising-malfunction-rate-over-time mechanic also contributes to that. It really does feel like you're a robot that is just breaking down and getting more and more glitchy. I love it.

Also, I found there were some satisfying puzzles in there! Level 9 really made me think and I had to restart it a couple times.

Strangely, level 10 seemed really easy? You can just go hit each of the three switches (the ones where you press G) and then you win? I think the design of level 10 might have gotten over-thought and you may have missed the obvious solution (I've been there, when designing puzzles!)

The only mechanic I didn't really understand is why pressing Repair always damaged the robot. I think it could have been useful to be able to repair in some cases, due to the spikes, although I eventually learned that you could press against a wall to change the spike cycle... so I guess the spikes are a pretty fair puzzle element (the player should be able to avoid any damage unless they malfunction).

Overall though, I really do think this is one of my favorite entries so far--the puzzle content was satisfying enough, and the malfunctioning mechanic was super cool. I also enjoyed the music. Great job!

Congratulations, nice entry! I loved the different puzzles, and I was amazed by how many levels are in the game! Furthermore, different mechanics are explored in the game, and that was really cool! 

I'm a bit perplexed about the core mechanic of "not doing what it should do", because it's not something really exciting or that changes the way you solve the levels... It just makes the levels longer. Maybe rethinking the malfunctioning effect in a way that benefits or changes the puzzle, would be an idea to improve the challenge and avoid a bit of frustration from the player. I read below that you were already considering other possibilities, so I would be glad to play the extended game!

Regardless, I had fun with your game, thanks a lot! :D
